WINDLASS FOR COMPRESSING BARRELS.

SPECIFICATION forming part of Letters Patent No. 292,817, dated February 5,1884,

" Application filed January 9, 1883. (N model.)

To all whom, it may concern Be it known that we,1EDWARD HOLMES and BRITAIN H oLMEs. citizens of theUnited States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new. and'useful Improvements in Power-\Vindlass for Barrels, of which the following is a specification.

The object of this invention is, to provide the means for drawing the free ends of the staves together after their opposite ends have been set up and secured within a truss-hoop, so that their edges will meet and be adapted to receive another truss-hoop for securing the staves in the form of a barrel-body which can be safely handled during the further operations required to complete the barrel, all of which will be fully and clearly hereinafter shown by reference to the accompanying drawings, in which Figure l is a side elevation, and Fig. '2 is a vertical section through line X X, Fig. 1.

A is the frame, which is supported in the usual way on legs a.

B is a vertically-movable rack securedfto the frame by a box, a so that it can be moved vertically up or down.

a represents a pinion securely fastened to the shaft Z, which is secured'in suitable boxes, b N, made in any well-known way. The outer end of the shaft I) is provided with a pulley, b rigidly secured thereto. The box If is fitted in vertical slideways 0, made in any wellknown way, so it will have an easy vertical movement up or down, and thereby impart a similar movement to the pulley b 0 is an arm jointed to the box I) by a pin,.

0 and to a foot step or treadle, 0 by a pin, d. The rack B is provided with two arms, 0*, jointed thereto at their lower ends by bolts d. Their upper ends, 01*, are bent orformed as shown in Fig. 1, and are provided with rollers (1 which roll in guideways d for keeping them in position within the frame.

' E represents an adjustable bar having a series of perforations, 6, through either of which one of said bars is jointed to the top of each of the arms 0 by a pin or bolt, and each bar E is provided with a holding-piece, e, to which the ends of the eablee or its equiva lent are rigidly fastened.

F represents thedriving-pulley, arranged 'ily understood.

shown in Fig. 1.

l to run in suitable bearings, f, which bearings are made vertically adjustable by means of the screws and jam-nutsf f The drivingpulley shaft G is provided with a small pulley, g, the face of which is covered with leather g, or other similar equivalent material, for the purpose of increasing the friction between the pulleys b and y, when 1110011132101]. The object in making the driving-pulleys vertically adjustable is to allow for the wearing of the leather'or other covering on the pulley 9. At the moment the edges of the staves of the barrel are brought together by the cable or truss-rope the movement of the compressingforce must cease, or either the barrel will be injured or the cable or truss-rope broken;

' hence the necessity of operating the machine by means of the friction between the pulleys d and g, which will give or slip when the staves are brought together, as above men tioned, and thereby prevent the breaking of the machinery. The pinion a gears into the rack B.

Theoperation of the invention will be eas- WVhen the end of the barrel adapted to be operated upon, as hereinbefore mentioned, is placed within the truss rope or cable 6 a pressure of the foot on the treadle brings the pulleys b g in contact with sufficient force to operate the machine, so as to raise the rack B and bring the arms c",

which act together as a toggle-joint, into the position shown by the dotted lines 43 t" i i in Fig. 1, thereby bringing the staves together so that a truss-hoop may be put on, as before mentioned. When the pressure is taken off the parts all resume their normal position, as It will be noticed that while using the machine the driving-pulley and friction-pulley g are kept in motion by a belt arranged in the usual way.

, In some cases the pulleys F and may be dispensed with and the driving-belt applied directly to the pulley b in such a manner as to slip when the necessary strain has been iven. The pulley I) would have to be providedwith flanges, arranged in any well-known way, to prevent the belt from running off while slipping,-but we prefer the arrangement above do not confine ourselves to the precise arrangement shown for giving such motion, as there are many other ways for giving the necessary reciprocating movements to said toggle-joi11t for instance, an additional togglejoint having an arm connecting it with a crank to a suitable mechanism on the driving-pulley, or by a small steam cylinder and piston of sufficient length to give the movements, or a screw c011- nected thereto in any well-known way may be used for giving such movements.

Some of the advantages resulting from the employment of a toggle-j oint are that the ends of the cable are drawn in opposite directions, so that the staves are all evenly and simultaneously moved together, thereby bringing them together more truly and with less danger of breaking any of them than if the strain all came from one side. Furthermore, a toggle-joint moves more quickly on the start, but slower and with increasing power as the mo tion proceeds, which also renders the staves less likely to break than if the power was applied from one side only. Besides the power increases as the resistance increases, just when it is required.

If desired, the parts B may in some cases be dispensed with and the cable connected directly to the parts (Z of the togglej oint levers.

\Ve claim- 1. The pulley If, secured to a shaft, I), having a pinion, a", in combination with the rack B, toggle-joint c, and cable a, substantially as and for the purposes described.

2. The pulley I)", secured to a shaft, I), havin g a pinion, a, in combination with the rack 13, arms 0*, adjustable perforated bars E, and truss cable or rope e, substantially as set forth.

3. A windlass for barrels, consisting of the frame, the pulleys F g, and the pulley 2), arranged in a shaft having a pinion, a, and capable of a vertical movement, substantially as specified, in combination with the movable rack B, toggle-joint, arms 0', holding-bars E, and the cable or truss-rope, for the purposes described.
